how to flush out diesel fuel? on 1990 Ford Thunderbird SC

my car had diesel fuel put in it and was drove between 2 and 3 miles home. the car has not been ran since. how do i flush the car out and do you think the car will be okay if its flushed and filled with unleaded?

The car should be OK if you can get enough of the Diesel out of the gas tank. The Diesel won't really hurt anything but it won't burn in a gasoline engine. Whether you can drive the car depends on what percentage of fuel is Diesel. You may have to get the tank drained but don't worry about the engine.
